A gray or gray-black powder with a hexagonal crystal structure. Melting point 2900 °c; Hardness (HV) 34g Pai density 4.52. Abrasion resistance, acid and alkali resistance, strong electrical and thermal conductivity, small coefficient of thermal expansion, excellent chemical stability and thermal resistance. Titanium diboride in air oxidation temperature up to 1000 deg C, stable in HC1 and HF acid.
titanium boride of abrasive grade and electronic grade was prepared by vapor deposition using titanium tetrachloride and boron trichloride as raw materials at 800 to 1000 ° C. Under the action of Hz.
titanium diboride and its composites have broad application prospects. Titanium diboride can be used with TiC, TiN, SiC and other materials to form composite materials, which are used for wire drawing die, extrusion die, sand nozzle, sealing element, cutting tool, armor protection and other materials, ideal materials for functional devices. As the cathode material of aluminum electrolysis cell, the power consumption of electrolytic aluminum is reduced and the service life of the electrolytic cell is prolonged due to the Good wettability of TiBz and metal aluminum liquid. The PTC Fever material and the flexible PTC material, which are reinforcing agents for metal materials such as Al, Fe, and Cu, can also be manufactured.
The product is non-toxic, packed with iron drum, and the lid must be tight and firm.
